[0002] In laboratory fields such as biotechnology, drug development, and clinical diagnostics, pipetting workstations are increasingly widely used as essential tools for automating liquid sample processing. Through precise robotic arms and positioning systems, pipetting workstations enable rapid and accurate transfer of liquid samples, significantly improving experimental efficiency and accuracy. However, as experimental requirements continue to increase, higher demands are being placed on the guiding and positioning devices of pipetting workstations.

[0003] Traditional pipetting workstations typically use manual or semi-automatic methods to position and move the storage tank. Manual methods are not only cumbersome and inefficient, but also susceptible to human error, leading to inaccurate positioning and liquid spillage. Semi-automatic methods, such as slide rails and sliders, guide and position the pipetting tip. However, after prolonged use, wear and error accumulation can cause a decrease in positioning accuracy. Therefore, it is necessary to design a new guiding and positioning device for pipetting workstations. Utility Model Content

[0021] A push plate 515 is movably sleeved on the outer wall of the adjusting screw 514, and the push plate 515 is slidably connected to the moving hole 512. A storage tank 516 is provided on the inner side of the push plate 515.

[0022] The outer wall of the placement plate 511 is fixedly installed with a limiting installation plate 517, and there are two sets of them, located at the front and rear of the placement plate 511 respectively.

[0023] A support vertical plate 518 is fixedly installed on the top of the limiting mounting plate 517. A C-shaped mounting plate 519 is fixedly installed on the inner side wall of the support vertical plate 518. Guide wheels 5110 are evenly installed at equal intervals inside the C-shaped mounting plate 519 through connecting shafts, and the guide wheels 5110 are located behind the storage liquid tank 516.

[0024] Furthermore, in this embodiment, a motor 513 is provided to drive the adjusting screw 514, which precisely controls the position of the storage liquid tank 516 within the moving hole 512. With the assistance of the guide wheel 5110, the storage liquid tank 516 moves smoothly and is positioned accurately. With the help of the positioning adsorption anti-slip head 5210, it fits tightly against the storage liquid tank 516 under the action of the second spring 528.

[0025] Example 2: Please see Figures 1-4Furthermore, based on Embodiment 1, the positioning part 52 includes: a connecting horizontal plate 521, which is fixedly installed on the outer wall of the limiting mounting plate 517; an adjusting groove 522, which is evenly and equidistantly opened on the top of the limiting mounting plate 517; an adjusting plate 523 is slidably connected inside the adjusting groove 522, and an adjusting rod 524 is fixedly installed on the outer wall of the adjusting plate 523, and the adjusting rod 524 movably passes through the connecting horizontal plate 521 and extends to the outer wall of the connecting horizontal plate 521.
